Description
Technical field
The invention belongs to technical field of medical instruments, particularly relate to medical disposable soft-connection parallel multi-tube hirudin anticoagulant blood-collecting connector.
Background technology
Because China's present medical level development is unbalanced, the renewal speed of armarium also is uneven, thus exist clinically always disposable fast, a large amount of blood sampling operating barrier.Traditional method is that the nurse cooperates a traditional vacuum blood taking tube (connected mode of this blood taking needle and blood taking tube is a tandem) with the blood taking needle that is flexible coupling, clinical needs are taken a blood sample in a large number, and (according to the clinical examination needs) to tend to occur the blood sampling volume of a traditional vacuum test tube not enough, need to increase by 1～2 blood taking tube, at this moment the process of operation of will occurring drawing blood is slow, complicated, complex operation, occur error easily, cause confusion easily, increase nurse's workload and error rate.Long behind the blood outflow human body with the anticoagulant binding time, be easy to generate the accuracy that haemolysis influences assay, wait a series of problems.China's traditional soft interconnection system blood taking needle has following shortcoming at present:
1, traditional soft interconnection system blood taking needle does not link to each other with vacuum test tube, needs medical worker's connections when drawing blood operation such as nurse.Traditional design makes medical worker such as nurse increase operation link when blood drawing; Increase the probability of makeing mistakes; Increase workload; Be unsuitable for clinical blood drawing operation a large amount of, quick, that concentrate.
2, do not have anticoagulant in the traditional soft interconnection system blood taking needle, contain anticoagulant, so after the clinical blood drawing, need put upside down mixing (blood combines with anticoagulant is better for convenience) immediately 5-8 time at vacuum test tube.
3, packaging material are too much, are unfavorable for environmental protection and reduce medical waste.
4, price height increases national medical insurance.
5, owing to not adding any anticoagulant in traditional blood taking needle and not linking to each other, so anticoagulant is added in the vacuum test tube with vacuum test tube.The tradition anticoagulant mostly is chemicals, and every kind of chemicals can only be at specific test item, heparin, sodium citrate, potassium oxalate, Na
2EDTA, K
2Traditional anticoagulant such as EDTA can not replenish mutually, can not exchange.Even so on blood taking needle, add heparin, sodium citrate, potassium oxalate, Na
2EDTA, K
2Anticoagulant such as EDTA, do not have in all senses yet and also can make troubles, increase misery (if on traditional blood taking needle, add traditional anticoagulant, patient's inspection item just need be more than 2 kinds) for the patient by many blood taking needles that the add different anticoagulant veins that puncture for clinical blood drawing check.
The People's Republic of China's " Chinese pharmacopoeia version in 2005, first one, the 57th page of record " Hirudo (HIRUDO) ", this product is the dry all of Hirudinidae animal whitmania Whitmania pigra Whitman, Hirudo Hirudo nipponica Whitman or Folium Salicis Babylonicae Hirudo Whitmania wranulata Whitman, summer, Qiu Erji catch, scald extremely with boiling water, dry or the low humidity drying.Concoct: Hirudo is cleaned, cutting, drying.Scald Hirudo: get water purification trematodiasis section, water to little with Pulvis Talci according to the method for scalding and heave.Function with cure mainly: removing blood stasis, removing blood stasis stimulates the menstrual flow.Be used for the blood stasis amenorrhea, injury from falling down.
Foreign medical science blood transfusion and 1993 the 16th volumes of blood fascicle the 6th phase record Chinese Academy of Medical Sciences Blood Research Institute, Guo Juan summary Wang Hebi examines and revises " progress of lepirudin 023 ludon " Haycraft and found in the Hementaria officianalis extract anticoagulant substances is arranged in 1884.At the end of the fifties, Markwardt isolates pure product first, called after hirudin (Hirudin), and know that it is the special inhibitor of thrombin, be a kind of ideal anticoagulant, antithrombotic preparation.Learn its structure and amino acid sequence the beginning of the eighties.Loaded down with trivial details because of the natural hirudin extraction step, and raise the Hirudo difficulty, the Hirudo source is deficient, is difficult to obtain the pure product of q.s, and research and clinical practice are restricted.In recent years, the development of technique for gene engineering has remedied this defective, utilize chemosynthesis, cDNA library, PCR method to obtain gene clone, express and obtain lepirudin 023 ludon, thereby pharmacology, pharmacodynamics and the toxicity etc. of hirudin have more in depth been studied, a large amount of zooperies and clinic trial have been accelerated hirudin and have been applied to clinical process.
The structure of hirudin: natural hirudin is not contain polysaccharide, by the single chain protein that 65 or 66 amino acid residues are formed, and molecular weight about 7,000, be rich in dicarboxylic amino acid, no Arg, Met and Trp, there are three intramolecular disulfide bonds to be positioned at peptide chain N-end, molecular configuration is played Stabilization; The C-end has more acidic amino acid residue, and a sulphation Tyr is arranged; The peptide chain middle part has one by Pro-Lys
47The special construction that-Pro forms, it plays a part certain in hirudin and thrombin interaction.
In 11 kinds of variants of hirudin, only variant I, II and III have anticoagulating active.
So far, all can obtain active lepirudin 023 ludon through escherichia coli or Yeast system expression, and be desulfurization acidic group hirudin, promptly 63 Tyr do not have sulphation.Reorganization has isomorphic map mutually with natural prodcuts.Further can produce multiple variant.
Along with the molecular biology develop rapidly, external at present existing tens companies develop lepirudin 023 ludon and the plain preparation of functional Hirudo, a large number of experiments show that recombinant products is similar to natural prodcuts, are effective anticoagulant and antithrombotic preparation.
